INJECTOR.

SPECIFICATION forming part of Letters Patent No.` 532,297, dated January 8, 1895. Application filed May 21,1894. Serial No. 5l1,9'77. (Model.)

To all whom t may con/cern,.-

Be it known that I, BENJAMIN MARTIN THROOP, of Geneva, in the county of Ashtabula and State of Ohio, have invented a new and Improved Injector, of which the following is a full, clear, and exact description.

The object ofthe invention is to provide a new and improved injector, which is simple and durable in constructiomvery effective in operation, and arranged to utilize the motive power to the greatest advantage.

The invention consists in certain parts and details, and combinations of the same, as will be hereinafter fully described and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in allthe views.

Figure l is a sectional side elevation of the improvement. Fig. 2 is a sectional plan view of the same, on the line'2-2 of Fig. 1. Fig. 3 is a like view of the same, on the line 3 3 of Fig. 1. Fig. 4 is a similar view of the same, on the line 4 4 of Fig. l; and Fig. 5 is a like view of the same, on the line 5-5 of Fig. l.

The improved injector is provided with an y injector casing A, formed at one side with a steam inlet B, coupled in the usual manner with the steam pipe C of the boiler or other source of steam supply. In the bottom of the steam inlet B, is held the nozzle D operating in conjunction with the discharge nozzle D', the said nozzles-D and D' forming a set of lift nozzles in the water inlet E, coupled or otherwise connected with the water supply pipe F.

The discharge nozzleD' ot the set of lift nozzles discharges into the compartment A' of the casing A, into which also extend the nozzles G and G', forming a set of forcing nozzles, of which the nozzle G is the steam nozzle and connects with a steam chamber' H, while the other nozzle G' is the discharge nozzle andopens into the outlet I, coupled or otherwise connected with the pipe .I leading to the boiler or other place to which the water is to be forced.

The steam compartment H is adapted to be connected with the steam inlet B, by a conical valve K mounted to turn in a seat A2 arranged in the casing A, the outer end of the said valve being provided with a suitable handle K' under the control of the operator, for connecting the steam compartment l-I with, and disconnecting it from thepsteam inlet B. The connection between the steam inlet B and valve K is made by a port a, and a similar port b is adapted to' connect the steam compartment H with the said valve K. See Figs. 1 and 2.

The lower end of the valve K is connected by a reduced stem K2 with a second conical valve K3 'mounted to turn in a valve seat A3 arranged in the lower end of the casing A, and extending into the compartment A'. This valve K3 is adapted to connect the interior of the compartment A' with, or disconnect it from the outlet I, and for this purpose the ports c and CZ are formed, ot' which the port c serves to connect the compartment A with the port K4 in the valve K3, the said port K4 opening into an overtlow aperture K5 formed centrally in the said valve K3 and leading to the outside of the casing. The other port CZ serves to connect the outlet I, with a port K6 formed in the Valve K3, and likewise leading to the overflow K5 previously described.

The valves K and K5 are arranged in such a manner that when the valve K closes or disconnects the chamber H from the steam inlet B, then the valve K3 connects the compartment A' with the outlet I, and when a quarter turn is given to the valve handle K', then the steam inlet B is connected with the compartment H, and the compartment A' is dis-` connected from the outlet I.

The nozzle D previously described is provided with a pressure increase nozzle D2, connecting at its upper end by a channel e with ports fopening into the interior of the valve K, the said channel c and ports f being con- IOO vof the casing.

compartment A. The Water can flow from the bottom of the latter through the ports c and K4 to the overflow K5 and to the outside The operator noW turns the valve handle K either to the right-or to the left so as to gradually close the port c by the valve K3, to permit Water to accumulate in the compartment A until it finally rises and IloWs through the nozzle G into the outlet I, and through the still connected ports CZ and K6, to the overflow K5. As the port cis gradually closing, the ports a and b are connected with each other by the valve K, so as to admit steam into the compartment H, the steam passing through the nozzle G, to act on the Water flowing down the nozzle Gr', thus forcing the Water. As the operator continues to turn the handle K', the port CZ is gradually closed by the valve K3, so that Water instead of going through the overflow K5, is now forced into the pipe Jleading to the boileror other place. The instrument has now reached its normal capacity, but as the operator continues to turn the valve K, the portsf Will be brought into register with the channel c, so that steam can pass from the inlet B, port a, valve K, portsf and channel e to the increase pressure nozzle D2, so as to give additional force to the Water and thereby increase the capacity of the device. The handle K has now been given a full quarter turn, so that the ports c, d, as previously mentioned are completely closed and the ports ct, b,fand channel e are opened.

The injector described is very simple in construction, can be comparatively cheaply inanufactured, and easily manipulated to force waterunder either normal or increased pressure to the boiler or other place.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. An injector, comprising an injector casing having a steam inlet, a Water inlet and ap outlet, and an interior compartment, a set of lift nozzles connecting the steam and water inlets with the said compartment, a set of forcing nozzles connecting the said compartment with the outlet, and a double valve arranged in the said casing and adapted to connect the steam inlet with the steam nozzle of the set of forcing nozzles and the said co1npartment With the outlet, substantially as shown and described.

2. An injector, comprising a casing having a central compartment into Which Water is discharged from the lifting nozzles, a set of forcing nozzles extending into the said cornpartment and discharging into the outlet of the casing, and a valve for connecting the said compartment With and disconnecting it from the outlet of the casing, substantially as shown and described.

3. An injector, comprising a set ot lifting nozzles, a set of forcing nozzles, a valve intermediate the said sets of nozzles, and a steam pressure nozzle for the said set of lifting nozzles and having its steam inlet controlled from the said valve, substantially as shown and described.
